Abstract

The invention discloses a self-locking railway fastener high in continuity and convenient to install. The self-locking railway fastener comprises a pre-buried inserting base (1) and a III type elastic strip (2), a cavity (4) is formed in the right portion of the pre-buried inserting base (1), a top cover (5) is arranged at the upper portion of the cavity (4) in a covering mode, a wedge-shaped portion (6) is arranged at the bottom of the top cover (5), a wedge-shaped block (7) is arranged in the cavity (4), a bolt (8) pushing the wedge-shaped block (7) to move in the first direction is arranged on the pre-buried inserting base (1), the inserting end of the III type elastic strip (2) is installed in an inserting hole (3), and the heel end of the III type elastic strip (2) abuts against the upper surface of the top cover (5). The self-locking railway fastener high in continuity and convenient to install has the advantages that the buckling pressure and bouncing stroke of the elastic strip to a steel rail can be adjusted, continuous longitudinal height adjustment of the fastener is achieved, the installation mode is greatly simplified, the self-locking railway fastener has the self-locking function, and transverse displacement of the elastic strip can be avoided.

Description

technical field [0001] The invention relates to the technical field of devices for fixing railway tracks, in particular to a self-locking railway fastener that can be continuously adjusted in height and is easy to install. Background technique [0002] my country's type III railway fastener refers to the "e" type fastener whose shape is similar to British Pandrol and French P+. It was developed in the early 1990s and is a new type of rail fastener used in the track structure of seamless lines. , because of the advantages of fewer parts and less maintenance, many existing domestic railway systems currently use Type III clip fasteners. Type III clip fasteners have insertion ends, heel ends, and toe ends connected in sequence. Installed in the socket of the pre-embedded insertion seat, the heel end is pressed against the upper surface of the insertion seat, and the toe end is used for pressing the rail. Type III clip fasteners are a development direction of railway fasteners in ...
